In the magnetic drag type of tachometer a transducer produces an analog signal in the form of a continuous drag due to eddy currents induced in an aluminium cup
The induced current is proportional to speed

Construction And Working

It consists of a rotor which is coupled to the rotor shaft of the machine whose speed is to be measured
A permanent magnet is attached to the rotor which rotates within an aluminium cup alongwith the rotor
A spindle is attached to the aluminium cup to which a pointer is fixed as shown in figure
A h ....etc

ABSTRACT

Changes in the lung air volume change the conductivity distribution in the thorax. Based on this effect, we describe a noncontact instrument to measure lung volume which is suitable for applications such as monitoring of breathing in sleeping subjects for sleep apnea. The instrument is based on a magnetic coil is positionned in a flexible mattress underneath the subject. AM frequency current is applied to the coil to generates Eddy currents in nearby conductive tissues, which in turn generat ....etc

EDDY CURRENT BRAKES

EDDY CURRENT:
It is a swirling current set up in a conductor in response to a changing magnetic field.
By Lenz's law, the current swirls in such a way as to create a magnetic field opposing the change

Eddy Current Brakes
It slow an object by creating eddy currents through emi which create resistance, and in turn either heat or electricity.
Braking action is made by varying the strength of the magnetic field.
A braking force is possible when electric current is passed through the electromagnets.

THEORY OF OPERATION

Changes in the volume of pulmonary air change the conductivity distribution in the thorax. On the basis of this effect, we describe an instrument without contact to measure the volume of the lung which is suitable for applications such as monitoring of respiration in patients of sleep for the sleep apnea. The instrument is based on a magnetic coil and is positioned in a soft mattress below the subject. Current AM frequency is applied to the coil to generate eddy currents in the tissue near the drivers, which in turn generat ....etc
